hey guys getting mad boost spike in my 95 r33 gtst its automatic and when i give it a hit off the line or when it kicks back a gear the boost goes absolutely crazy and spikes up to 12 - 15 psi and the car just revs off its tits and goes nowhere and spits a SHITLOAD of black smoke........ can anybody help me with this problem??? or has anyone experienced this kind of thing before??? cuz i dont wanna fry anything..... any help would be much appreciated thanx

interesting you should say that.. as our stagea ( RB25DET NEO ) does the same thing.

I am not currently running a boost guage as everything is stock as a rock engine wise.

I think 1/2 the problem is the auto takes so freaking long to change gears.

so when you say it revs its tits off and does nothing.. is this just while its changing gears or after its engaged the gear? how many PSI are you running normally ( ie before it spikes )

what if you turn the boost down does it still happen?

everything in my engine bay is stock as a rock as well save for the fmic..... im running stock boost with a turbosmart boost tee boost controller wound all the way down so it should be running stock boost regardless.... normally before it spkies its running on 7 psi boost and it happens during both when the gear is engaged and also during gear change depending on the cirsumstances its f**kin weird

hmmm . . not to sound like an @sshole but those turbosmart boost controllers are notoriously crap!

they do tend to spike, I foudn the turbotech ones far better ( not to mention heaps cheaper ! )

so your factory boost solenoid has been removed yeh?

are you still running the stock BOV?

hmm .. re-reading your last post I see it happens ( the spike ) if your in gear or not.. that would make me even more suspicious of that boost T

the turbotech ones were well received by the people on this forum so I would be pretty surprised if

someone near you does not have one they can loan you jsut for testing reasons

it was spiking before we put the boost tee on there we put the boost tee on there to try and control it to keep the boost down and yeah still running stock bov i got the boost tee for nothing off a mate so yeah i dont know man... like i said it was doin it before i put the controller on there so i have no fkn idea lol

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
